Taoil it may concern;

Be it known that I, JACOB Bfiu'roEN, a

Kiel, Germany, have invented a newv and useful Pressure Resisting Receptacle, of which the following is a specification.

The present invention relates to pressure resisting receptacles which are arranged in the interior of the pressure-resisting hull of submarine boats and which serve for containing compressed air or the like.

The object of the invention is to provide receptacles *ofsthus type which are capable of withstanding great pressure and occupy only small space and require only small expenditure of material. 1

The accompanying drawings illustrate the invention by way of example. i

Figure 1 is a vertical longitudinal section. through a single pressure resisting recepe taole arrangedin the central part of a submarine boatwhi'h, part carriesfthe conning tower; Fig. 2 is a section online 2-'-2, Fig. 1, looking from the left; Fig. 3 a view corresponding to that shown in F1g. 1 and showing a plurality of pressure-resist ng reoeptacles, and Fig. 4 is a section on line 4-4, Fig. 3, looking from the left.

A indicates the pressure--res1st1ng body or hull of the submarine boat which carries the conning tower a and B indicates the pressure-resisting receptacle. The receptacle B is of bi-convex cross section (Fig. 2) and. is formed by a part of the wall of the pressure-resistin hull A, an arched partition wall C, which is preferably located in the lower portion of the vessel, with its tudinally of the boat, and two arched end wallsc Preferably, the wall C is less than a semi-circle and geometrically its radius is such that it intersects an approximately similar arc of the hull A.

In the embodiment of the invention shown in Figs. 3 and 4, two further pressure-resist-ing receptacles D and E are provided in addition to the receptacle B shown in Fig, 1.

, The receptacles D and E are formed by parts of the wall of the pressure-resisting hull A, arched partition walls F and .Gr

which extend longitudinally of the boat, and

arched end-walls f and g. A part of the walls of the receptacles D and is furthermore formed by parts of the wall G of-jthe receptacle B. Theffltvalls F and G are less than a semi-circle and they constitute arches sprung from theconvex side of v.th e wall C r to the walls constituting the hull A, Due to their flat cross-section the receptacles BD and E occupy only comparatively small space in the boat. As. a part'of-the. wall of the hull A is used in the receptacles the receptaolesonly require small expenditure of material and the receptatcles are capable of resisting great pressure from the inside as all the confining walls of the receptacles are arched.

Having thus described my inventgiomwhat I claim as new therein and desire'stef risecure by Letters Patent,is:-,

.1. 'In a submarine boat, a pressure resisting receptacle within the hull, said receptacle having abi-convex cross section and approximately rectangular length section,

the arcuate bottom of the hull constituting the bottom of said receptacle, an arcuate late-secured to the bottom at itspoints of intersection constituting the roofand two arcuate plates constituting the end Walls of said receptacle and being secured to the roof and the bottom.

2. In a submarine boat, thecombination with the hull of the boat, of a plurality of pressureresisting receptacles of 'bi-convex crosssection and rectangular length-section arranged in the interior of the boat and each having one of its longitudinallyjic'onfining walls formed by the wall of the hull, and a plurality of arched partition walls each forming the second longitudinal confining wall of the receptacles; one of said partition walls forming part of the confiningwall of several of said receptacles, and arcuate plates forming end walls of said receptacle- 3. A submarine boat comprising a'hull of circular cross section forming a. central chamber, an arched or curved inner wall extending longitudinally of the boat, supported from the curved wall of the hull,

with its chord substantially horizontal, two 0 arcuate end walls forming'with the inter-1 sected portion of the hull a pressure resisting chamber within the hull of bi-convex' cross section and rectangular lengthsection.-

4. A submarine boat comprising ahu-lll having a curved bottom wall, an archedj'or' curved inner wall extendinglongitudinally; of the boat, supported from the curved wall of the hull, with its chord substantially horizontal and forming with the-interscctedft'hfi portion of the hull a pressure resisting chamber; said hull also having curved or arched walls extendin, *pwardly from the convex side of said lower arched wall, to the side walls of the hull and forming with said lower and side Walls, additional pressure resisting chambers.

5. In a submarine boat, the combination with an arcuate longitudinal outer wall of the hull, an arcuate longitudinal inner wall disposed so as to intersect the outer wall, the radii of the arcs formed by the two walls being equal, and arcuate, transverse walls, said walls forming a pressure resisting inner chamber of bi-convex cross section and rectangular length section.

6. In a submarine boat, the combination with a hull, a plurality of interior partition walls disposed so as to intersect the hull, to form pressure resisting receptacles of biconvex cross section and rectangularlength section, one of said partition walls intersecting and supporting the other partition walls.

' pressure 7. In a submarine boat, the combination 2 with the hull of the boat, of a plurality of resisting receptacles arranged therein having bi-convex cross section and rectangular length section, a series of partition walls forming part of the confining 3 walls of the receptacles, one of said walls forming a part of the confining wall of each of the pressure resisting receptacles. 8. In a submarine boat, the combination with an arcuate outer wall, a plurality of 3 arcuate partition walls disposed so as to intersect said outer wall and form pressure resisting receptacles, one of said partitions disposed so as to support the other partition walls.
